Answer:
Sum of the solutions of 
is -9.
Product of the solutions of 
is 
Step-by-step explanation:
1.
Given:
The expression whose sum of the solution is required is given as:
For a quadratic equation of the form 
the sum of the solutions is given as:
Sum = 
Here, 
Therefore, the sum of the solutions = 
2.
Rewriting the above equation in a standard quadratic equation, we get:
For a quadratic equation of the form the product of the solutions is given as:
Product = 
Here, 
Therefore, the product of the solutions = 
Note the equal sign, what you do to one side, you do to the other side. Isolate the variable z.
First, subtract 3z and add 6/4 to both sides
4z (-3z) - 6/4 (+6/4) = 3z (-3z) + 1 (+6/4)
4z - 3z = 1 + 6/4
Simplify. Note that 1 = 4/4.
z = 4/4 + 6/4
Simplify. Combine like terms
z = 10/4
Simplify. Change the improper fraction into mixed fraction and simplify.
z = 10/4 = 2 2/4 = 2 1/2
